General annotation (Comments)

Function

Extracellular dipeptidyl-peptidase which removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline. Contributes to pathogenicity. Ref.1

Catalytic activity

Release of an N-terminal dipeptide, Xaa-Yaa-|-Zaa-, from a polypeptide, preferentially when Yaa is Pro, provided Zaa is neither Pro nor hydroxyproline.

Subcellular location

Secreted Ref.1.

Sequence similarities

Belongs to the peptidase S9B family.

Biophysicochemical properties

pH dependence:

Optimum pH is 7.0-9.0. Ref.1
